OK, I found that the crankshaft has .013 endplay/ clearance. The manuals say .003-.009. I can move the crank back and forth and see the movement and hear a "clunk". The main bearings are still torqued. The rods are removed. Would .013 (.004 more than suggested) cause my noise, you think? I'm trying to decide the right way to remove the main bearing cap. It has the oil pick up tube & screen attached.Thanks.
